ICE BOAT Filed March 25, 1962 United States Patent 3,1tl9,665 1 3E BDAT .lorgen Remmen, 257 E. lt larlret St, Bethlehem, Pa. Filed Mar. 23, 1962, er. No. 131,d76 1 Claim. (Cl. 28il1l6) This invention relates to new and useful improvements in ice boats equipped with sails and mounted on runners, and it is among the objects thereof to provide an ice boat having four regular main runners and four auxiliary runners on extended runner planks to prevent capsizing.

It is a further object of the invention to provide specially designed runners having one edge touching the ice and another edge clear of the ice so that they will not act as brakes as would a V-type runner heretofore used.

The invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:

FIGURE 1 is a side eievational view of an ice boat embodying the principles of this invention;

FIGURE 2, a rear view thereof;

FIGURE 3 a top plan view diagrammatically illustrating the fuselage and runner planks of the ice boat;

FTGURE 4 a rear elevational view of the front runner plank pivot having a runner mounted thereon;

FIGURE 5 a rear view of the rear runner plank with a modified form of rear runner;

FlGURE 6 a similar view of another modified form of rear runner; and,

FIGURE 7 a similar view of a modified form of auxiliary runner.

in the drawing, the numeral 1 designates a longitudinal frame structure or fuselage made of lightweight material having runner planks Z and 3 attached thereto. The runner planks 2 and 3 have main runners designated by the reference numerals 4 and 5 and 6 and 7. Planks 2 and 3 are also provided with fixed auxiliary runners ti and 9 and 1t} and 11, respectively, on extended runner planks. A tiller 12 is provided for steering. Steering rod 13, with adjustment, connects the two front main runners t and 5 by screw pins in the steering lever, not shown. A mast 14 extends from substantially the center of the ice boat and is rigged for sails 15 and 216.

The front runner 5, as shown in FIGURE 4, is an inclined runner and by moving it from one side to the other, either edge can be used as the running edge. It is mounted on runner carrier or pivot 18 in runner plank 2 and the runners are provided with reinforcing bars 19. In FIGURE 7, the auxiliary runner 9 is shown mounted by a bracket 29 to the runner plank 2. The rear runner 7 is shown mounted by bracket 21 to the runner plank 3 in FIGURE 5 and is also shown as having a chamfered face 22 which makes outside edge contact with the ice arsasss Patented Nov. 5, 11%??? even though the bracket is straight and not tilted as in the remaining figures of the drawing. A modified form of the main runner is shown in FIGURE 6 in which the runner E1 is mounted by a bracket 23 to the runner plank 3.

In operation the runners being tilted at approximately a 26 angle, have the outside edge touch the ice, leaving the inside edge clear of the ice. The front runners 4- and 5 should toe out slightly by adjusting the steering rod 13 which, when it is once adjusted, need not be touched again. By virtue of the outer edge con-tact, the runners will not act as a. brake when they are toed out, which was a bad feature of the V-type runners used in earlier fourrunner boats. The inclination of the mounting brackets of the runners is 20. However, the front runners may be used in the rear and the rear at the front, making them interchangeable.

The auxiliary runners are to steady the boat and may be set straight.

By means of the four-runner design, the boat is inherently more stable than the three-runner boat. The extension of the runner planks has the effect of increasing the leverage, thereby increasing stability still further, and prevent the boat from capsizing. By means of the inter changeability of the runners, their life is greatly extended.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

In an ice boat, the combination of a fuselage with a mast, said fuselage having longitudinally spaced front and rear transverse runner planks, a main runner spaced from each end of said planks and extending below the bottom of said fuselage a sufficient distance to clear the latter with the ice surface on which the runners rest and an auxiliary runner adjacent the ends of said planks spaced outward from said main runners, said main runners being connected by an adjustable steering rod to etfect a slight toeing out of said runners and said auxiliary runners extending below the bottom of said fuselage a lesser distance than said main runners to be normally out of contact with the supporting ice when the ice boat is in upright position.
